The characteristics of the Bohr model allow you to find that the correct answer for the distribution of particles in the atom is:
b) Ten protons would be located in the nucleus, and 10 electrons would be on the outside of the atom orbiting in rings.
The bohr model was initially developed for hydrogen, where it manages to fully explain the spectrum of the hydrogen atom, it was quickly spread to other multi-electronic atoms with the characteristic of having a single electron in their last orbit.
The extension to atoms with more than one electron in the last shell the model results are not completely correct.
The Bohr model uses Rutherford's knowledge that the atomic nucleus is a very small part of an atom that contains all its mass, that is, it contains the protons and neutrons and the electrons are in circular orbits around the nucleus.
In the case presented of Neon, its electronic configuration is
1s² 2s² 2p⁶
Let's examine the different claims:
a) False. Protons and neutrons form the mass of the atom, therefore they are both in the nucleus.
b) True. The protons are in the nucleus and the electrons are in circular orbits.
c) False. All protons and neutrons must be in the nucleus, plus neon only has 10 neutrons.
c) False. The number of protons determines the type of atom. An atom with twenty protons is Calcium atom .
In conclusion, using the characteristics of the Bohr model we can find that the correct answer for the distribution of particles in the atom is:
b) Ten protons would be located in the nucleus, and 10 electrons would be on the outside of the atom orbiting in rings.

Explain the formation of planets based on our knowledge of the solar system
Planets form from particles in a disk of gas and dust, colliding and sticking together as they orbit the star. The planets nearest to the star tend to be rockier because the star's wind blows away their gases and because they are made of heavier materials attracted by the star's gravity.

The positively charged subatomic particles are called protons. The mass number of an atom is the sum of number of protons and neutrons and the atomic number is the number of protons.
What is an atom?An atom is the basic unit every substances. It is made up of subatomic particles electrons, protons and neutrons. The positively charged particles are called protons. Whereas electrons are negatively charged.
The atomic number is the number of protons and the mass number indicates the sum of number of protons and neutrons.
Water can be classified as a diatomic molecule formed from two hydrogens and one oxygen atom. Among the given, malleability is a physical property. It is the ability to change the shape and size of metal blocks.

When baking soda and vinegar react bubbles are produced. What mostly occurred?
Answer:
a chemical reaction
Explanation:
Answer:
When vinegar comes in contact with baking soda, a cascade of two chemical reactions takes place. The result is carbon dioxide gas—a product of the reactions—bubbling up in a water solution. The bubbles create the fizz and sizzling sound.Baking soda is bicarbonate (NaHCO3) and vinegar is acetic acid (HCH3COO). One of the products this reaction creates is carbon dioxide, which makes the bubbles. When the baking soda meets the vinegar, there is a chemical reaction as carbon dioxide gas is created and fills the balloon causing it to inflate.

How much heat is needed to raise the temperature of 100g of an iron from 25°C to
110°C?
(The specific heat of iron is 0.45 J/g∙°C).
Answer:
382.5J
Explanation:
Use the formula:
E = mcΔθ or Q = mcΔT
m = 100g
c = 0.45 J/g°C
ΔT or Δθ = 110 - 25 = 85°
Sub in the values:
E = 100 × 0.45 × 85
= 382.5J

A mixture of neon and argon gases exerts a total pressure of 2.39 atm. The partial pressure of the neon alone is 1.84 atm, What is the partial pressure of the argon?
Answer:
0.55 atm
Explanation:
According to Dalton's law of partial pressures,
The total pressure is the summation of the partial pressures of individual gases in a sample of non-reactive gases.
Since Neon and Argon are noble gases, they do not react with each other. So we can apply Dalton's partial pressure law.
P total = P Ar + P Ne
2.39 atm = P Ar+ 1.84 atm
P Ar = 2.39 atm - 1.84 atm
= 0.55 atm
According to the Dalton's law of partial pressure the partial pressure of the argon is 0.55 atm.
What is pressure?Pressure is defined as the force applied on an object perpendicular to it's surface per unit area over which it is distributed.Gauge pressure is a pressure which is related with the ambient pressure.
There are various units by which pressure is expressed most of which are derived units which are obtained from unit of force divided by unit of area . The SI unit of pressure is pascal .
It is a scalar quantity which is related to the vector area element with a normal force acting on it.It is distributed over solid boundaries and across arbitary sections of fluid normal to the boundaries at every point.
In this case, pressure of gas argon is obtained by subtracting pressure of gas neon from the total pressure ,that is 2.39-1.84=0.55 atmosphere.
Thus ,the partial pressure of gas argon in atmosphere is 0.55 atmosphere.
